This old comment stands out as possibly related: /* FIXME Cope with non-contiguous => splitting existing segments */ https://sourceware.org/git/?p=lvm2.git;a=blob;f=tools/pvmove.c;h=c5e39292228393d6d2ce0a21018dba5b5c306da5;hb=HEAD#l342 It seems you're trying to pvmove a range that covers two segments, which I guess doesn't work (I don't know why it doesn't check for this to provide a better error.) If you pvmove segments separately it should avoid that limitation (your test works for me if I do "pvmove /dev/loop0:18122768-18909199" which avoids crossing a segment boundary.) > Here is a short reproducer: > > ------clip------ > #!/bin/sh > > set -ex > > mkdir -p lvmtestdir > mount -t tmpfs none lvmtestdir > cd lvmtestdir > > truncate --size=$((156275497728*512)) testimg1 > truncate --size=$((46883372928*512)) testimg2 > > dev1="$(losetup -f --show testimg1)" > dev2="$(losetup -f --show testimg2)" > > pvcreate "$dev1" > pvcreate "$dev2" > > vgcreate TESTVG "$dev1" "$dev2" > > lvcreate --name=lv0 -l $((1048576+167398)) TESTVG \ > "$dev1":0+655360 \ > "$dev1":17037866+393216 \ > "$dev1":18909200+167398 > lvcreate --name=lv1 -l $((16382506+1478118)) TESTVG \ > "$dev1":917504+16120362 \ > "$dev1":655360+262144 \ > "$dev1":17431082+1478118 > > # ERROR > pvmove -v "$dev1":18122768-19076597 || : > > # cleanup > vgremove --force TESTVG > losetup -d "$dev1" > losetup -d "$dev2" > cd .. > sleep 1 # lvmtestdir busy? > umount lvmtestdir > ------clip------ > > > -- > Anssi Hannula > > _______________________________________________ > linux-lvm mailing list > linux-lvm@redhat.com > https://www.redhat.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/ _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
